Definitions

  • the invention relates to a balance with a weighing chamber, partially from is limited to a fixed part of the scale and of at least one Sidewall, a front wall and a cover wall, of which at least one of Walls for opening and closing the weighing chamber by means of a Guide device is movable.
  • Such a balance is known, for example, from EP-A-0 234 008. It acts It is a scale with a scale and with a pan on all sides enclosing weighing room, with a fixed front glass, one laterally to each Rear sliding sliding door, a rear sliding upper Cover and one connecting the sliding doors with the top cover Holder, with the holder when opening and closing the side walls and / or the cover wall by means of bearings with these moved and thus the access to the weighing room, can fully release without obstructing webs on the sides. Also, the two side walls can be used individually or synchronously together, with or be moved without the cover wall. The shift can be done by motor or by hand, wherein in manual mode to be moved discs from the drive be decoupled.
  • EP-A-0 574 668 a balance is disclosed having an upper cover wall of a Windscreen housing, which by means of a manually operable lock is fastened or removable. After removing the cover it is possible both the front wall and the side walls for the purpose of cleaning completely remove from the case.
  • the Cover wall Part of a windscreen housing cohesive frame, the However, the walls below a certain web freedom, and thus a better view of the interior of the windshield housing, admitted, however, for some applications are not quite satisfactory yet. For one thing it is not possible to dispense with the upper frame, on the other condition this Also perform some manipulation on the bars, with high precision must be made to align with the receiving recesses.
  • the invention is therefore based on the object, a good accessibility of the Weighing room in a simple manner or with little manipulation for the Secure supply of supply lines.

  • the walls are in the position of use in guide elements of Guiding device positively locked. The unlocking takes place for all walls by a single hand movement.
  • mounts for the movable walls are present, which integrated into the guide devices are, in addition to the dismantling for the purpose of cleaning a free accessibility ensured the weighing room, whereby even in the closed state of the Wägeraums no obstructive webs are available. Otherwise, the Possibility of the front wall as well as the movable walls by a simple to bring manual actuation into a stable inclined position.
  • the balance has a Additional unit, which is located at the rear end of the scale, for example.
  • These Additional unit contains supply units and / or control units. With Feedthroughs connected to this unit can be connected via special on Scale housing mounted guide troughs the recesses in the walls of the Libra will be spent. Thus they do not interfere disturbing the displacement of the Side walls.
  • a balance 1 according to FIG. 1 consists of one, the rear wall 9 and the bottom 8 the weighing chamber 4 forming fixed part, which is a part of the Weighing technology containing floor space 2 and a substantially the Comprising drive mechanism housing 3, and the weighing chamber. 4
